CHAIR Filed Nov. 5, 1938 Patented Oct. 1, 1940 W tudinally" collapsedwhen in Vfolded position, "thereby providing a constructionrequirng lessstorage `space than the ordinary folding chair, and furthermoreproviding a chair whichjwhen folded and longitudinally collapsed may beconvenientlyhandled and carried, and which, if

desired,"may be carri-ed in a holder `or caseof a length materially lessthan that which would be requiredforthe ordinary collapsible chair whenfolded.

`It is an object of this invention to provide a" combination folding andcollapsing chair of simplified and inexpensive construction, 'which froman `erected `position may be conveniently and Arapidly folded and thenlongitudinally col` lapsed;` `k

It is also an object of this invention to' provide a chair of thefolding type, which when notinv use .can be conveniently folded, afterwhich the seat I"and back are slidably lowered with respect to the legsto afford a compact construction.

" It" isa further object of' this invention to providea chair of thefolding type having the seat and back hingedly connected together tocontact one another when the `chair is in folded position,`

allowingboth the seat and back to be slidably moved with respect to thechair legs to reduce the normal folded height or over-al1 length of thechair when not in use. a

It is furthermore an object of this' invention to provide a combinationfolding and collapsible chair wherein both the seat and back have sepa`rate sliding intertting relationship with a pair of the chair legs,allowing the chair when folded tohave the seat and back moved intocontact with one another and slidably lowered with respect to the chairlegs.

It is an important object of this invention to provide an improved typeof combination folding and collapsible chair of inexpensive and simpleconstruction having pivotally connected short and long legs, said longlegs having shiftably engaged therewith hingedly connected seat and backmembers whereby the chair when folded t may have the height or lengththereof reduced by slidably shifting the seat and back with respect tothe length of the chair.

Other and further important objects of this invention will be apparentfrom the disclosures in the specication and the accompanying drawing.

`Figure 6 is an enlarged fragmentary detail section taken on the lineVI`VI ofV Figure 4; l

As shown inthe drawing: l l l `The improved combination folding andcol--y lapsing chair comprises a pair of long or main` legs I which areconnected attheir lowerends by means of a transverse frontrung or round2L Also connecting the two main legs I, inter` mediate the ends thereof,is a transverse supporting bar or cross strip 3 which connects and tbraces l the intermediate portions of the two main legs I. l The innerside of each of the main legs I is provided with an upper orchair backguide groove 4 and 'with a lower or chair seat guide groove 5, asclearly illustrated in Figure 2. Pivotally connected to each of the mainor long legs I, on the outer sides thereof, `is an auxiliary or shortervleg 5, by means of a pivot bolt I or the like. The lower ends of the twoauxiliary or shorter legs 6 are connected by means of a rear brace rungor round 8. The upper `ends of the two 'shorter legs 6 are connected bya brace or tie rod 9, which when the chair is in extended or openposition for use, serves as a front support for the chair seat.

Associated with the long legs I is a chair back I and a chair seat II.The chair back Ill is provided with an arched lower opening I2. Rigidlyengaged in the opposite side edges of the chair back IIJ are pivot andguide pins I3, the projecting ends of which project into the upper guidegrooves 4 provided in the long legs I of the chair. As clearlyillustrated in Figure 2, the lower margin of the chair back I0 ishingedly or pivotally connected to the rear margin vof the chair seat IIby means of hinges I4. Rigidly UNITED STATES rATENToFI-ICEV ISIS securedto the side margins of the chair seat II and projecting outwardlytherefrom are opposltely positioned guide pins or pintles I5, the endsof which project into the lower guide grooves 5 provided on the innersides of the long legs I of the chair.

Secured to the bottom of the chair seat II, near the front end thereof,are two hook brackets I6 adapted, when the chair is opened up asillustrated in Figures 1 and 2, to releasably hook or engage over thefront brace rod 9 connecting the upper ends of the shorter or auxiliarylegs 6 of the chair. When the chair is folded and ready to be collapsed,as illustrated in full lines in Figure 4, the hook members I6 engageover the cross bar 3 connecting the long or main chair legs I. When thechair is opened or setup for use, as illustrated in Figures 1 and 2, therespective sets of legs I and 6 cross one another, with the main legs Iprojecting downwardly and forwardlygwhile the auxiliary legs 6 projectfrom the bottom of the seat II downwardly and rearwardly. When the chairis opened-up for use, the hook brackets I 6, as the seat drops intoposition,engage over the brace rod 9, thereby affording a means forlimiting the spread of the cross chair legs,'assisted by the guide pinsI3 of the chair back I-Il,as said guide pins reach the upper end of theguide groove 4.

if With the chair in open position, the rear portion of the seat IIrests upon the cross brace 3r connecting the legs I, thereby providing adouble support for the seat II. When the chair is not needed, the samemay be readily folded and then collapsed into a compact form, requiringvery little space for storage. To collapse the chair, it is onlynecessary toswing the lower end of the back forwardly and at the sametime swing the seat II upwardly into contact with the back I, as shownin dotted lines in Figure 4, after which the seat and back by their ownweight are adapted to slide downwardly between the main legs I until theguide pins or pintles I5 of the chair seat reach the lower ends of theguide slots 5, in which position the hook brackets I6 on the bottom ofthe `chair seat II engage over the brace bar 3. VIt will thus be notedthat the chair is first folded and then collapsed to shorten theassemblage byzpermitting the folded seat and back to be dropped from theuppermost position thereof, illustrated in dotted lines in Figure 4,downwardly between the legs of the chair to materially shorten theheight or over-all length of the combination folding and collapsingchair. As the chair is being folded and collapsed, the auxiliary orshort legs 6 of the chair, being released by the brackets I6, pivotallyswing, by the action of gravity, into position adjacent the outersurfaces of the main legs I to provide a collapsed structure wherein allof the members of the chair are positioned in substantially the sameplane.

It will thus be seen that an improved type of chair is providedadaptable for use as a beach chair, a camp chair, a card table chair andone readily adaptable for many other uses. One of the important featuresof the chair is the shortening of the over-all length of the chair whenin collapsed position, by the dropping of the collapsed seat and backdownwardly between the long legs of the chair and after the initialfolding operation has been accomplished. The telescoping of the seat andback downwardly between the legs of the chair materially reduces theoverall length of the collapsed chair, permitting the chair to be moreconveniently handled and adapting it to be conveniently placed in asuitcase, a carton or the like of a size materially smaller than wouldbe required for the reception of the ordinary type of folding chairwhich, when folded, is materially higher than the height of the chairwhen in open position.

It will, of course, be understood that many features of construction maybe Varied through a-wide range without departing from the principles ofthis invention, and it is, therefore, not the purpose to limit thepatent granted hereon otherwise than is necessitated by the scope ofthe.

appended claims.
